Question about Vestax Pmc07pro DJ Mixer System

White noise in left channel on my Vestax PMC 06 pro-a DJ mixer

Its not an earth buzz kind of sound, its more like the roar of static on a TV or radio not tuned in, it can only be heard when the channel is switched to phono, i have tried switching the line/phono selector for the other channel's and it makes no difference. The noise can still be heard with nothing plugged in and listening through just headphones. Music can still be played through the channel, but the static roar is still in the background. It cannot be heard with the volume fader down. the noise is only heard in the left of the stereo output (or in the left ear of headphones), and the eq controls have no effect on it. any help would be greatly appreciated!

Replace U1 on the input board.

Use a TL 082 IC available for 2 dollars from Radio Shack.

Align the IC the same as the old one.

This IC is nect to the wires that are glued to the board and does RIAA equalization for the turntable input.

Try it with nothing plugged in to the inputs, if there is no noise. most likely its the turntable, cd player, or whatever the input is is the problem. or try plugging the mixer into a different area of the house/room. its like if you were to put your cell phone by a mixer, or speakers.

Noise , sounds like ungrounded, all the cables are fine , the connection is grounded


so its a buzzing noise. are your turntables grounded? some dont have to be. the buzzing could be several things feedback from something around you or the mixer is buzzing cause of to much power. just mess around w stuff your not gonna break it. and what i mean about that is more wires check wires. dont preform open heart surgery on your equptment. sometimes the buzzing means the faders are going i own 3 vestax mixers and on my pmc 17a right before the faders went i had massive buzzing sound.

Hello! We have some problem whith 1 chanel, when 2


BOTH turntables and the same channel on each? If it's really really low and tinny that would probably be a failure to have/use a PHONO preamp (built-in and selectable on the Mixer).

Swap the channels coming in from the mk1200 and see if it stays with the mk1200 or with the left channel of the mixer.

There IS an outside chance you have flaky connections at the cartridge.

If mixer is working properly, check the rating of the adapter versus what the unit requires. Some sites indicate this requires a 12 volt adapter rated at 1.2 amps.

The right output channel on the right side of my pmc 05 pro 4 has very low output. I can hear both right and left output channels in the headphones when I have the cue selected but when I try to monitor...


I assume you swapped thee output leads as well as the inputs which you di mention, to verify you amps and cables...
The Vestax schematic I have is NOT your same model, but the companies often re-use circuitry. In the schematic I have it appears that the two channels go through two levels of NJM2068L op amps.
In these two levels there is both a master gain control. It is important to know whether the gain control varies the output level of the right, even if it is low. Also in this gain control area is a master balance pot which varies the ratio of the left and right and is CAPABLE of taking either channel to near zero output... IF you have that control check it for sure !!! The pot is a dual employing both an A taper and C taper which is a reverse of the A.
The right tool for troubleshooting this is an oscilloscope, but first an inspection looking for board cracks around the output and pot area is in order.

probably just a cold solder joint on the power plug inside the mixer. Check with a meter, then repair(resolder) if needed.
